Afternoon Tune: 'The Rains of Castamere' by The National (from Game of Thrones)

Many fans of HBO's Game of Thrones are still reeling after last night's gruesome episode. But some (mainly those who have not read the novels) may still be wondering where the name of the episode, "The Rains of Castamere," comes from.

The name refers to the song played by Walder Frey's musicians just following the bedding ceremony at his daughter's wedding. The song is referenced often in the novels as a Lannister victory tune.

The haunting version recorded for season two's soundtrack was laid down by The National with lyrics from George R.R. Martin's novels. It can be heard in bits and pieces throughout season two, and in its entirety during the the credits of the ninth episode, "Blackwater," where the Lannisters defeat Stannis Baratheon in battle.

While The National's version is not heard in last night's episode, the harrowing melody remains and serves as a chilling backbone to the episode's startling events.
